The month is still young. We're still hammering away on the kit and will have information as soon as we're ready. Stay tuned.
In other words, get ready for disappointment as we're nowhere near ready. That hard to plug it into Steam Workshop hmmm? See how dangerous it is to give vague, standard PR 101 answers to your fans? We might just completely misunderstand you...

It's not that we have to wait. It's that we're being strung along that is causing unhappiness.
"The CK ships with the game"
"Oops, we made a booboo. The CK will only be available shortly after launch."
"Oops we made another booboo. We forgot that all our bases are belonging to Steam and have to integrate the CK with their Workshop. Sometime in January and don't expect to hear from us again until we want to talk to you."
"Oops, we can't make the integration work. So sorry. Just wait." is probably next.
Stop hinting at dates and then retracting. Either tell us when or just tell us you don't have a clue.
